Scheduling with time clock controls turns lights on and off, sets lighting levels for different times of day and changes the lighting profile for after-hours mode. More sophisticated systems also respond to signals sent from external control devices such as sensors or switches.

Paraffin wax is usually produced as a by-product of oil refining. It has a molecular weight which is usually less than half that of most polyethylene waxes. Because of this and other differences, paraffin wax usually has a much lower melt point and is softer than most polyethylene waxes.5.t has a molecular weight which is usually less than half that of most polyethylene waxes.
